A second trans-spliced RNA leader sequence in the nematode Caenorhabditis elegans.
In the nematode Caenorhabditis elegans, the 22-nucleotide RNA sequence called the spliced leader (SL) is trans-spliced from the 100-nucleotide-long SL RNA to some mRNAs. We have identified a trans-spliced leader (SL2) whose sequence differs from that of the original spliced leader (SL1), although both are 22 nucleotides long. By primer-extension sequencing, SL2 but not SL1 was shown to be prese...
متن کاملSpliced leader trans-splicing
on the forests, wildlife, and indigenous people of this area, WWF warns. It is not necessary to use this area as there is already a total of 2.3 million hectares of idle or derelict land available for palm oil plantations in Kalimantan, an area greater than the proposed plantation, WWF points out. In addition, oil palm is not recommended for planting in areas more than 200 metres above sea leve...
متن کاملSpliced-leader trans-splicing in freshwater planarians.
trans-Splicing, in which a spliced-leader (SL) RNA is appended to the most 5' exon of independently transcribed pre-mRNAs, has been described in a wide range of eukaryotes, from protozoans to chordates. Here we describe trans-splicing in the freshwater planarian Schmidtea mediterranea, a free-living member of the phylum Platyhelminthes. Analysis of an expressed sequence tag (EST) collection fro...
متن کاملTrans-spliced leader addition to mRNAs in a cnidarian.
A search of databases with the sequence from the 5' untranslated region of a Hydra cDNA clone encoding a receptor protein-tyrosine kinase revealed that a number of Hydra cDNAs contain one of two different sequences at their 5' ends. This finding suggested the possibility that mRNAs in Hydra receive leader sequences by trans-splicing. This hypothesis was confirmed by the finding that the leader ...
متن کاملSpliced leader RNA trans-splicing discovered in copepods.
Copepods are one of the most abundant metazoans in the marine ecosystem, constituting a critical link in aquatic food webs and contributing significantly to the global carbon budget, yet molecular mechanisms of their gene expression are not well understood. Here we report the detection of spliced leader (SL) trans-splicing in calanoid copepods. We have examined nine species of wild-caught copep...
